Supply Chain Performance (SCP) depends on several factors additionally its length and the yield of its members. However, manage a Supply Chain (SC) means well managing knowledge as sharing them between actors involved in this process. Knowledge Management (KM) has, of appearance, a direct impact on SCP, but its formalization remains always ambiguous. In this context, this paper aims to determining the KM impact on the SCP through highlighting the relation between KM Elements (KME) and SCP Evaluation Criteria (SCPEC). Our approach consists, in the beginning, to position the knowledge concept in the SC through a conceptual model that identifies the KM impact on SCP based on mutual relations. Afterward, we adopt the House Of Quality (HOQ) to evaluate and measure the impact of each KME on whole SCPEC, similarly, the impact of whole KME on each SCPEC. An implementation example is proposed in the end.
